| population differentiation and nuclear gene flow in the dominican anole (anolis oculatus). | allele frequency data from nuclear microsatellite loci were used to investigate patterns of nuclear gene flow and population structure in the morphologically variable dominican anole (anolis oculatus). all six loci used proved to be highly polymorphic, with an average of 18.8 alleles per locus. test for hardy-weinberg equilibrium revealed small numbers of heterozygote deficiencies at single loci in single populations and consistent patterns of increasingly significant heterozygote deficiency in ... | 2002 | 12207719 |
| common garden and natural selection experiments support ecotypic differentiation in the dominican anole (anolis oculatus). | the theory behind ecotypic differentiation and ecological speciation assumes a predominant role for natural selection working on characteristics with genetic variance, but experimental support for these assumptions is limited. lesser antillean anoles show marked ecotypic variation within islands and the potential for ecological speciation. common garden rearing experiments on the dominican anole (anolis oculatus) suggest that the characters showing geographic variation have genetic variance and ... | 2005 | 15791540 |

| the dynamics of natural selection and vicariance in the dominican anole: patterns of within-island molecular and morphological divergence. | the larger islands of the lesser antilles are ecologically and geologically complex and are inhabited by single, but morphologically variable, anolis species. although earlier work has indicated that a large part of the morphological variation in anolis oculatus from dominica can be attributed to selection, a history of recurrent volcanic activity over the last few million years suggests that vicariance may have also played a significant role. we report a study of variation in the cytochrome b g ... | 2000 | 10937201 |
| recent biological invasion shapes species recognition and aggressive behaviour in a native species: a behavioural experiment using robots in the field. | invasive species are a world-wide threat to biodiversity. yet, our understanding of biological invasions remains incomplete, partly due to the difficulty of tracking and studying behavioural interactions in recently created species interactions. we tested whether the interactions between the recently introduced invasive lizard anolis cristatellus and the native anolis oculatus in dominica have led to changes in species recognition and aggressive behaviour of the native species. the use of realis ... | 2020 | 32221966 |
| the effect of recent competition between the native anolis oculatus and the invasive a. cristatellus on display behavior. | invasive species are a global threat to biodiversity. cases where the invasion has been tracked since its beginning are rare, however, such that the first interactions between invasive and native species remain poorly understood. communication behavior is an integral part of species identity and is subject to selection. consequently, resource use and direct interference competition between native and invasive species may drive its evolution. here, we tested the role of interactions between the r ... | 2018 | 29922509 |
